CARBURETER.

SPECIFICATION forming part of Letters Patent No. 606,998, dated July 5,1898.

Application led January 13,1898. Serial No. 666,586. (No model.)

To @ZZ wtom it may concern:

Be it known that l, JOHN A. MOGOWAN, a citizen of the United States,residing at Maywood, in the county of Cook and State of Illinois, haveinvented a certain new and useful Improvement in Carbureters, of whichthe following is a full, clear, concise, and exact description,reference being had to the accompanying drawing, forming a part of thisspecification.

My invention relates to a carbureter, my object being to provide animproved apparatus for readily and efficiently manufacturing gas fromany of the hydrocarbon oils, as naplitha, gasolene, benzene, and thelike. Y

I provide a furnace in the bottom of which is provided acombustion-chamber and above which is placed the generating-chamber. Theoil is admitted at the upper end of the generator and falls upon aseries of plates arranged `obliquely end to end and in reverseorder fromtop to bottom of the generatingchamber. Coils for superheatedsteam orair surround the generating-chamber in the space between the same andthe Walls of the furnace, whereby they are subjected to the heat fromthe combustion-,.chamber, and the su-Y perheated air or steam isadmitted to the lower end of the generating-chamber, rising andcarryingthe generated gas out of the chamber through a pipe or ductconnected with the top thereof. The walls of the generatingchamber, aswell as the oblique plates therein,

become highly heated, and the oil as it drops into the chamber and flowsdown the heatingsurfaces thereof is converted into a gas by the highlieatland is carried from the chamber by the superheated air orsteam. Aportion of the generated gas is led through a branch pipe to agas-burner for suppl ying gas to the combustion-chamber. The Oil-'may beadmitted to the generating-chamber b`y gravity or by air-pressure.

I have illustrated my invention in the aC- companying drawing, in whichthe generator is shown in section.

Like letters refer to like parts in the draw- Ing.

1Within the furnace d is provided a genen ating-chamber b, beneath whichis the combustion-chamber c, heated by the gas-burner CZ.Surroundingthechamberbarecoiledpipes e, through which air is passed fromthe tank f, the air being heated and passing into the lower end ofgenerating-chamber b through nozzle e. The pipes e, instead of beingconnected with an air-tank, may be connected with a steam-generator. Theoil-inlet pipe g opens into the chamber ZJ at the upper end,

being connected with oil-tank g', supplied 6o with air under pressurethrough pipe f to force the oil into chamber Z9. l/Vithin chamber ZJ arearranged the oblique plates Zz ZL, placed end to end in reverse order.These plates may be made from a single piece of metal bent at intervalsto form the several oblique members. A flue Za extends from the upperend of the furnace, and a gas-exit Z extends from the upper end ofchamber l) and extends to the gas-mains or other place where 7o the gasis to be utilized. A branch pipe Z extends from pipe Z into the burner1CZ.

In operation the burner CZ heats the lower end of the chamber c, andth'e heat passing upward heats thewalls of the chamber and thesuperheating-pipes e. The Oil dropping into the top of thegenerating-chamber strikes the oblique plates and flows along the same,being spread over the surfaces to thereby completely subject the same toheat and convert 8o the oilinto gasf The oil iiows down the upper fac ofthe first oblique plate, along the under side of the second plate, andso on, being thus completely subjected to the heat and the draft ofsuperheated air or steam. The superheated air or steam entering bynozzle e carries the gas out through duct Z and part thereof passes bybranch pipe Zl to burner CZ to feed the llame in the combustion-chamber.

Having described my invention, what I 9o claim as new, and desire tosecure by Letters Patent, is-

The combination With an outer shell or casing, of an inner shell, anannular space being formed between the same, a series of coiled pipessituated in said annular space and opening into said inner shell, aspace being provided beneath the bottom of said inner shell toconstitute a combustionchamber, an oilinlet at the top of said innershell, a series roo of oil-distributing plates Within said inner scribedmy name in the presence of two Wtshell, a gas-outlet leading from theupper end nesses.

of said inner shell, and a branch ipe leadino* therefrom to a nozzle fordireotinlg a flame o? JOHN A MCGOWYAN 5 gas into saidcombustion-Chamber, substan- Vitnesses:
